Lieutenant Dan, a personal trainer, was interested in whether or not there was a linear relationship between the number of visits his soldiers made to the gym each week and the average amount of time they exercised per visit. He took the following data.  Soldier  1  2  3  4  5  6  Number of visits per week  1  3  4  2  3  5  Average time spent exercising per visit (hours)  2  1.5  1  2  2  0.30  Using the best fit line, estimate the average time spent exercising per visit for 4 visits per week. Please explain how you derived the answer
